High level network advice request
by Richard Nilsson 31 Jan '20

31 Jan '20

High level network advice request :) I have a self-hosted engine deployed on a node, Ovirt v. 4.3. I am testing, but I don't understand the big idea of how to set-up Ovirt networking for hosted / engine-managed virtual servers. I would like to host a few virtual servers for things like Next/OwnCloud, SuiteCRM, NethServer or others. For example, I know exactly how set-up a virtual machine with a centos / lamp stack on a fedora host, I can make a network bridge for the vm with fedora cli, then use haproxy (or squid) as a reverse-redirect server to allow WAN access to the vm server using FQDNs. What is a good strategy for Ovirt hosting a webserver? To use the default ovirt management network for the virtual server machines doesn't seem like a best practice? Should I make a new logical network for the virtual servers? Do I need to configure bridges for the machines? It looks like bridges and virtual NICs are automatically configured when I make the network and virtual machines, is that right? Is it the usual or typical practice that one ovirt logical network uses only one network bridge to a one physical NIC? Would all of the kVMs on the logical network share the same / single bridge of the particular network? I'm not sure what the big idea should be, what is a best practice? I wonder, should I bond several physical NICs, then point the bridge, for a new / dedicated logical network for webservers, to the the bonded NICs? There is more than a little new vocabulary for me to onboard for Ovirt / virtual / logical networks...I will greatly appreciate, and I thank you in advance for any top level / best practice advice!

Assign permissions from within the VM portal?
by nicolas＠devels.es 31 Jan '20

31 Jan '20

Hi, We're testing version 4.3.8, we're planning to upgrade to this version in production as currently we're still using 4.1.9. In 4.1.9, users could grant permissions on their created VMs to other users from within the VM portal, however I can't find this option on version 4.3.8. Permissions granted to users so they can create and handle their VMs are VmCreator and DiskProfileUser on the DataCenter. Is there a way to allow users grant permissions on their VMs to other users in the VM portal? Thanks

FOSDEM 2020 - AMENDMENT In Memory of our Friend, Lars Kurth
by Doron Fediuck 31 Jan '20

31 Jan '20

Hi all, For those of you who are unaware of this, Lars Kurth from the Xen project has passed away [1]. Lars was one of the people who truly practiced open source and worked with the oVirt project on running FOSDEM's Virtualization and IaaS room in the past years. In Lars' memory there will be a special session [2] on Sunday morning, which will be broadcasted live. You're all welcomed to join physically or via the live stream. Thanks, Doron [1] https://lists.xenproject.org/archives/html/xen-announce/2020-01/msg00004.ht… [2] https://fosdem.org/2020/schedule/event/vai_memory_of_lars_kurth/

problem with qemu / dynamic_ownership
by Christoph Köhler 31 Jan '20

31 Jan '20

Hey, is the problem back with qemu/dynamic_ownership? We have one DC with two clusters: one: vdsm-4.30.38 / libvirt-4.5.0-23, two: vdsm-4.30.40 / libvirt-4.5.0-23, LibgfApi enabled, Gluster-Server 6.5.1, Gluster-Client 6.7, opVersion 60000 It went well for a log time but now, with getting vdsm like above, we are getting old problems: °setting disk files to root:root when VM went down °cannot create snapshot etc. Do we have to set dynamic_ownership=0 in qemu.conf? We were testing anything but nothing other worked. Is there any idea? Christoph

Re: [ANN] oVirt 4.3.7 Third Release Candidate is now available for testing
by Strahil 31 Jan '20

31 Jan '20

I got upgraded to RC3 and now cannot power any VM . Constantly getting I/O error, but checking at gluster level - I can dd from each disk or even create a new one. Removing the HighAvailability doesn't help. I guess I should restore the engine from the gluster snapshot and rollback via 'yum history undo last'. Does anyone else have my issues ?

Virtual disk attached to VM showing in the Webui but not identified by the system
by Eugène Ngontang 30 Jan '20

30 Jan '20

Hi, I'm facing a virtual disk behavior I don't understand. Currently my VMs are spun up with a Boot disk of 25GB and an additional disk of 215/45/65 GB depending. When logged to the webui I see the two disks, but when I ssh to VM we only see the primary boot disk, the other one can't get a *UUID* and then cannot and is not mounted I also noticed in the webui the second disk doesn't have a logical name as you can see in the screenshot. Pleas can someone explain this behavior please?

Details about bios and custom emulated machine values
by Gianluca Cecchi 29 Jan '20

29 Jan '20

Hello, in oVirt 4.3.7 in "Edit VM" -> System -> Advanced parameters I can choose Bios Type: Default Q35 Chipset with Legacy BIOS Q35 Chipset with UEFI BIOS Q35 Chipset with SecureBoot and Custom Emulated Machine: Use cluster default (pc-i440fx-rhel7.6.0) ... q35 pc-q35-rhel7.3.0 pc-q35-rhel7.4.0 pc-q35-rhel7.5.0 pc-q35-rhel7.6.0 and I can apparently mix all possible values. Any deeper information about implications? What is the "Default" value for Bios Type? Did anything change in 4.3.8 (eg official support for q35)? I search also through official docs for RHV 4.3 (virtual mgmt guide, appendix A), but for example I don't find any reference to the "Bios Type" parameter and a vague reference to the "Custom Emulated Machine". Is there any more detailed link? Thanks, Gianluca

Got everything installed and was uploding an ISO when the system just stopped responding. Went to the host and saw the hostedengine was paused. Looked online and found the following instructions for unpausing it virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf resume HostedEngine And get the following error Failed to acquire lock: No space left on device any ideas?

Very new to this, trying to work my way through it. Got everything up and running, was uploading an ISO to try and start a vm and then everything just disconnected. On the host it shows the hostedengine as paused. Did some digging and found the suggestion to do the following: virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf resume HostedEngine which gives me the message Failed to acquire lock: No space left on device.

Hello Experts. In version 3.5.2.1-1.el6, we used an "ovirt-shell -E action..." command to start/stop virtual machines from command line. In version 4.3.7.2-1.el7 ovirt-shell is deprecated. Please advise how to start/stop them from command line. vdsm-client provides only destroy/shutdown/reset/cont, nothing about startvm or poweron. Regards.

ovirt_vm ansible module -- how to wait for ova export to finish
by Jayme 27 Jan '20

27 Jan '20

I wrote a simple task that is using the ovirt_vm module https://docs.ansible.com/ansible/latest/modules/ovirt_vm_module.html -- it essentially loops over a list of vms and exports them to OVA. The problem I have is the task is deemed changed once it successfully submits the export task to oVirt. This means that if I gave it a list of 100 Vms I believe it would start an export task on all of them. I want to prevent this and have it only export one VM at a time. In order to do this I believe I will need to find a way for the task to wait and somehow verify that the export was completed before submitting a task for the next VM export. Any ideas? - name: Export the VM ovirt_vm: auth: "{{ ovirt_auth }}" name: "{{ item }}" state: exported cluster: default export_ova: host: Host0 filename: "{{ item }}" directory: /backup/ with_items: "{{ vms }}"

Hi Team, I need a quick help from you. I need to upgrade ovirt host server from 4.1 to 4.2 version but i am getting below errors :- --> Finished Dependency Resolution Error: Package: nfs-ganesha-nullfs-2.3.3-1.el7.x86_64 (@ovirt-4.1-centos-gluster38) Requires: nfs-ganesha = 2.3.3-1.el7 Removing: nfs-ganesha-2.3.3-1.el7.x86_64 (@ovirt-4.1-centos-gluster38) nfs-ganesha = 2.3.3-1.el7 Updated By: nfs-ganesha-2.5.5-1.el7.x86_64 (ovirt-4.2-centos-gluster312) nfs-ganesha = 2.5.5-1.el7 Available: nfs-ganesha-2.5.2-1.el7.x86_64 (ovirt-4.2-centos-gluster312) nfs-ganesha = 2.5.2-1.el7 Available: nfs-ganesha-2.5.3-1.el6.x86_64 (ovirt-4.2-centos-gluster312) nfs-ganesha = 2.5.3-1.el6 Available: nfs-ganesha-2.5.3-1.el7.x86_64 (ovirt-4.2-centos-gluster312) nfs-ganesha = 2.5.3-1.el7 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest This host server also have hosted engine running on it. I am using local storage for hosted engine. Can any one help on above. Thanks Shashank

gluster shard size
by Alex McWhirter 24 Jan '20

24 Jan '20

building a new gluster volume this weekend, trying to optimize it fully for virt. RHGS states that it supports only a 512mb shard size, so i ask why is the default for ovirt 64mb?

Re: KVM (libvirt) VM Import
by jorgevisentini＠gmail.com 24 Jan '20

24 Jan '20

Hi Paul, thanks for your reply. I imported the VM with the command below, but I had that create a Export Domain on oVirt for this task. Only problem this task is that is in two parts, first part is export to Export Domain, on NFS, and second part is import on oVirt through of the Export Domain. This was the only way I managed to import. virt-v2v -ic qemu+ssh://root@10.255.255.23/system TEMPLATE-WINDOWS2019 -o rhev -os 10.255.255.22:/export --network TEMPLATE-WINDOWS2019 Thanks again.

API OVA export - getting job id/job status
by lars.stolpe＠bvg.de 24 Jan '20

24 Jan '20

hi, I tryed this with API 4.2 and 4.3. purpose of the following script is, to export a given list of vm as OVA one after another. To reach that i need to monitor the job status and pause the script till the actual export is done. The script works fine, but not the restriction of the returned jobs to the one spcificaly job i need to monitor. Therefor the script pauses on *any* running job. the working script: #!/usr/bin/python import logging import time import ovirtsdk4 as sdk import ovirtsdk4.types as types connection = sdk.Connection( url='https://ovirtman12/ovirt-engine/api', username='admin@internal', password='***', ca_file='/etc/pki/ovirt-engine/ca-ovirtman12.pem', ) hosts_service = connection.system_service().hosts_service() hosts = hosts_service.list()[0] vms_service = connection.system_service().vms_service() vms = vms_service.list(search='name=blxlic954') for vm in vms: # print("%s (%s)" % (vm.name, vm.id)) vm_service = vms_service.vm_service(vm.id) start_time = (time.strftime('%Y%m%d_%H%M%S', time.localtime(int(time.time())))) vm_service.export_to_path_on_host( host=types.Host(id=hosts.id), directory='/nfs_c3/export', filename=('%s_backup_%s.ova' % (vm.name, start_time)), wait=True, ) # time.sleep(5) jobs_service = connection.system_service().jobs_service() jobs = jobs_service.list(search='') for job in jobs: print(job.id, job.description) # job = jobs_service.job_service(job.id).get() while job.status == types.JobStatus.STARTED: time.sleep(10) job = jobs_service.job_service(job.id).get() print('job-status: %s' % (job.status)) connection.close() The line jobs = jobs_service.list(search='') works fine as long as the search pattern is empty. if i try to restrict the results returned like this: jobs = jobs_service.list(search='description=*blxlic954*') i get an error: bad sql grammar [select * from (select * from job where ( job id in (select distinct job.job id from job where ( ) )) order by start time asc) as t1 offset (1 -1) limit 2147483647]; nested exception is org.postgresql.util.psqlexception: error: syntax error at or near ")" looks like the 'where' clause is not filled correctly. Am i wrong with my syntax or ist that a bug? Is there another way to get the correct job id/status?
